The GistThis is about as stacked as a system can get. There’s upside all over the field including the graduated prospects listed above. Granted, they are still prospects and where everybody ends up playing is a good question. Heading into 2015 we’ll all wait for the arrival of Kris Bryant and later in the year we’ll be chomping at the bit for Addison Russell’s debut. Meanwhile, Javier Baez might be one of the most polarizing players on this team and there’s a chance he could start the year in the minors. But that would just give fellow sophomore Arismendy Alcantara some more time at the keystone and he’s no slouch either. Even the rotation looks good with Jon Lester and Jake Arrieta one-two. Can the bespectacled one take this team to the promised land? *grabs popcorn*

The GistThis is a fun system for fantasy prospects and reminds me of the Rangers’ farm with a stud building block, toolsy outfielders, and a couple of nice arms to round things out. The Astros have talented young players surfacing on the major league team as well, with George Springer entering his sophomore season and Jake Marisnick in the mix for an outfield gig. I like Marisnick as a sleeper this year, as he’s always had that 20/20 type of profile and now finds himself in a better park for hitting. Jon Singleton needs some polish after hitting just .168 in his rookie year, but I’m still buying the 23-year-old in dynasties thanks to his power potential. Mike Foltynewicz and Rio Ruiz would have both been towards the top half of this list prior to being traded to Atlanta.

The GistNew general manager A.J. Preller wasted no time turning the league’s worst offense into the land of 1,000 outfielders this offseason. At the price of a few good prospects, Upton, Myers, and Kemp make up the new Padres starting outfield. Trea Turner, last year’s first round pick, is in a unique situation in that he’s technically been traded to the Nationals but will remain in the Padres’ minor league system until June. He ended up in top ten list limbo, but you can find some notes on him in the NL East roundup. Yangervis Solarte is projected to lead off and play third for San Diego, but both Will Middlebrooks and Cory Spangenberg could see time there this year. Keep them on the radar for NL-only leagues or deeper mixed formats. Spangenberg is technically still a prospect and as a utility infielder could also spell Gyorko at second base.

The GistHeading into 2015, the Cardinals have another strong farm system featuring interesting fantasy plays for the current season as well as down the road. As always one of the strengths of this system is its pitching, but there are also a handful of attractive outfielders. There’s plenty of young talent emerging on the major league squad as well. Kolten Wong is a sexy pick this year at second base and fellow sophomore Carlos Martinez could break camp in the rotation. It’s hard not to mention Oscar Taveras, who we lost before we really had the chance to see what he could do.

The GistThe Royals went all the way to the World Series in 2014, helped in part by the pitching of rookie Yordano Ventura. He averaged 96 on his fastball, second only to Garrett Richards. The 23-year-old will enter 2015 as the ace of the Royals’ staff. No pressure or anything. Brandon Finnegan, the Royals’ first round pick in 2014, contributed to the major league club as well. While he was impressive in the bullpen, it looks like the Royals will lean towards stretching him out in the minors. Other top prospects in this system will look to “bounce back” either from injury or disappointing performances. If you’re in need of a short-term prospect for this year Terrance Gore is likely to provide some stolen bases, but he’s behind Jarrod Dyson on a crowded outfield depth chart.

The GistThis system is full of risk/reward prospects with big ceilings. It’s also deep, and I had a hard time narrowing it down to just 10 to be honest. Fringe top ten guys like Keone Kela could help the major league bullpen as soon as 2016, and Kela’s triple-digit heater looks like the stuff of a closer. Then there’s Delino DeShields Jr. who was a Rule 5 selection from the Astros. DeShields hit 11 homers and stole 54 bases in Double-A last season. You can’t throw a stone without hitting a fantasy relevant prospect on this farm. Heading into 2015, Rougned Odor will get another extended look at second base while Jurickson Profar continues to battle shoulder issues. For what it’s worth, I still like Profar in dynasty leagues and at just 22 years old he still has plenty of time to get things back on track.

The title pretty much says it all, so instead of a big intro this opening paragraph will link you to some more helpful information regarding prospects. Here are the Top 30 prospects for 2015 redraft leagues. Here are the American League and National League Top 10 prospect indexes. We also have the Top 20 2014 signees for first-year player drafts in dynasty formats. Last but not least, here are my Top 100 keeper rankings. In the prospect rankings below, more specific ETAs are given as well as links to the organizational top ten list for each player.

Ages listed are as of Opening Day 2015. Here are the Top 50 prospects for 2015 fantasy baseball…

The GistThis is a strong farm system that boasts both talent up the middle and arms to bolster a young rotation headlined by Matt Harvey, Zack Wheeler, and Jacob deGrom. Noah Syndergaard and Travis d’Arnaud were acquired in the R.A. Dickey trade, and with Syndergaard arriving sometime this summer, Mets fans will finally see the fruits of that trade at Citi Field. Dilson Herrera should also stick in the majors at some point this season. One of 2014’s pleasant surprises was the recently graduated deGrom, who will look to build on a 2014 rookie campaign in which he posted a 2.69 ERA with 144 strikeouts in 140 innings pitched. After a demotion to Triple-A early in the year, Travis d’Arnaud also posted good numbers with 13 homers in 421 plate appearances.

The GistThe Rockies are a great system to turn to for big upside fantasy prospects. The fact that a few of these guys will one day call Coors Field their home park only adds to the appeal. If you haven’t bought in already, this might be a good time with several of the top hitters in this system expected to see at bats in the hitting-friendly California League this summer. The same can’t be said for the pitchers in this system, who take a large hit on this fantasy list compared to traditional prospect rankings thanks to the same park situation. Eddie Butler, who made his big league debut in 2014, fell off the list entirely thanks to a shoulder injury. The Rockies will see three new affiliations in 2015 – Albuquerque (AAA), New Britain (AA) and Boise (ss).

The GistThe Orioles’ farm is headlined by two solid pitching prospects, although both have dealt with elbow injuries of late. Dylan Bundy may see MLB time later this year along with hitting prospects Christian Walker and Dariel Alvarez. The top half of this farm is pretty solid from a fantasy standpoint, and the Orioles already have nice young talent at the major league level in Manny Machado, Kevin Gausman, and Jonathan Schoop. Gausman was a good arm to own in the second half of 2014 after yo-yoing in the first, and may take a major step forward this year. Meanwhile, Schoop popped 16 homers in his rookie campaign. Machado is still just 22 years old and obviously has massive potential. With a bounce back from Chris Davis, this could be a very nasty offense in 2015.
